SPECIFICATION forming part of Letters Patent No. 593,627, dated November 16, 1897.

Application led February 25, 1897. Serial No. 624,929. (No model.)

To all whom it may concern,.-

Be it known that I, JOHN WEIL, a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Telephones; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in telephones, and has more particular relation to devices vfor operating the call-circuits of the same.

The object of the invention is to provide a supportj for the receiver which will be operated by the weight of the same to actuate the Vgenerator connected to the bell-circuit.

nected to the bell-circuit; 4, the pivoted receiver-support, and 5 the segmental disk for operating the generator. The said support 4 is provided with a hook 6 at its outer end adapted to receive a suitable screw-eye attached to the receiver and is removably mounted upon the extended end of a shaft 7,

journaled in suitable bearing-plates 8 and 9, secured to said casing 1.V Said plate 8 is providedwith an extended hub 10, the office of which is to hold the support 4 a sufficient distance away from the casing 1 to prevent the receiver striking said casing as the said support is raised or lowered. Said shaft 7 is provided at its middle with an enlargement 11,

which lies between the plates 8 and 9 and thus prevents any longitudinal movement of said shaft within its bearings. The inner end of said shaft, extending within the casing 1,

is provided with a segmental disk 5, having atoothed periphery 12 and adj ustably secured to said shaft. by a set-screw 13. The teeth 'formed on the periphery of said segmental disk 5 engage a spur-gear 14, secured to the shaft 15 of the generator 3, which is connected to the bell-circuit. It will thus be observed that as the shaft 7 is rotated in either direction the segmental disk 5 is operated, thus Vcommunicating motion to the generator 3 and causing the bells of the bell-circuit to sound. rIfhe said shaft 7 is further provided with an adjustable laterally projecting arm 16, secured thereto by a set-screw 17 and pivotally connected at its outer end to a pendent rod 18. The lower end of said rod 18 is connected to a bow-spring 19, secured to the casing 1.

It will be observed from the foregoing description that when the receiver is removed from the hook 6 of the supporting-arm 4 the tension of the spring 19 at once forces the arm 4 up through the medium of the barlS, the

arm 16, and shaft 7 and operates the generator. Upon the receiver being replaced on the hook 6 the weight of the same overcomes the tension of the spring 19 and thus pulls the arm 4 downward and again rotating the segmental disk 5 and sounding the off signal. The said pendent rod 18 is pivotally connected near its lower end to a switch-lever 20, pivoted to the casinglat 21. The free Aend of said lever is adapted to normally engage and lie in contact with a spring contactstop 22, secured to the casing 1 and having electrical connection with the bell-circuit. When the receiver is removed from the hook 6, the resulting movements of the respective parts of the device cause the said lever 20 to be rotated upon its pivot and its free end to pass clear of the .contact 22 and contact with the contact-plates 23 23, which are connected to the receiver, the transmitter, and central stations, but not to the bell-circuit.

It will be observe-d from theforegong description that when itis desired to call up the central station the receiver 2 is simply removedpfrom the supporting-hook 6, which permits the arm 4 to rise under the tension of the spring 19 and thus operate the generator and sound the signal-bell until the free end of t-he switch-lever 2O passes clear of the spring-contact 22, when the bell-circuit is immediately broken and the receiver, transmit- IOO ter, and line circuits closed. After the telephone has been used the receiver is again hooked upon the arm 4, thus causing the same to descend and again operating the generator, thus ringing olf. As the said lever descends the main circuit of the receiver and transmitter is broken and the bell-circuit again completed ready for the next call.

It will also be observed from the foregoing description that the switching as well as the movements of the generator are altogether automatic and are simply incidental to the removal from or the application of the receiver to the supporting-arm. By the employment of myinvention the usual disagreeable operation of ringing up and ringing off is altogether avoided, and this ringing is accomplished automatically by the weight of the receiver, as before described. There is therefore no liability of the patron-forgetting to inform the central station that he has finished speaking, as the mere act of hanging up the receiver automatically accomplishes this result. It is the practice of a great many patrons of telephone-lines to leave the receiver hanging by its conneetingcord after use, and to guard against this and still render the device operative I connect the connecting-cord 24 of the receiver to the outer end of the arm fl by a suitable split clamp Q5, so that the weight of the receiver will be thrown upon the outer end of the arm whether it is hung up or simply permitted to hang pendent by its connecting-cord. The operation of the device when the receiver hangs in this manner is substantially the same as heretofore described, the weight being thrown on or off the supporting-lever as before described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination with a generator-box, of a shaft mounted therein, a lever pivotally mounted on said shaft and formed at its free end with a receiver-hook, a crank mounted on said shaft, a rod pivotally connected to the end of said crank, a bow-spring having one end secured to the casing of the box and the other pivotally mounted upon the lower end of the rod so as to normally force the same upward, a pivoted switch-lever connected to said rod, and contacting-points connected with the bell and main-line circuits and adapted to be engaged by said switch-lever, substantially as described.

2; The combination with a generator-box,

of a shaft pivoted thereon, a lever mounted on said shaft and having a receiver-hook at its free end, a segmental rack also mounted on said shaft and adapted to engage and operate the generating mechanism, a crank mounted on said shaft, a rod pivotally connected to said shaft, a spring connecting the lower end of said rod with the casing of the box, whereby the rod is normally forced upward, a pivoted switch-lever connected to said rod, and contact-plates adapted to be engagedby said lever and connected respectively to the main-line and bell circuits, substantially as described.

3. The combination with a generator-box, of a pivoted lever mounted therein and provided at one end with a receiver-hook, a clamping-arm rigidly mounted on said lever and adapted to clamp the receivercord rigidly between it and the said lever so as to support the receiver independently of the hook, means connecting said lever with the generator for operating the same, and a switch also connected to said lever and adapted to shift the circuits upon the movement of the latter, substantially as described.

4. The combina-tion with a generator-box, of a shaft journaled therein, a segmental rack having an apertured sleeve loosely mounted upon said shaft, a screw mounted in said sleeve for securing said rack to said shaft, a lever provided with a sleeve also loosely mounted upon said shaft, a screw mounted in said latter sleeve and adapted to secure it to the shaft, a lever mounted upon said shaft and provided at one end with a receiver-hook, a generator adapted to be operated by the segmental rack, and a switch connected to said shaft adapted to be operated upon its rotation, and a switch connected to the lever adjustably mounted upon the shaft so as to be operated upon the rotation of said shaft; the construction being such that the relative arrangement of the segmental rack and the adjustable lever may be changed at will by loosening the screws and turning the respective sleeves upon the shaft, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

JOHN VEIL.
